Randomized Controlled Trial Comparative Study
Comparison of the Truview PCD™ and the GlideScope(®) video laryngoscopes with direct laryngoscopy in pediatric patients: a randomized trial.
The GlideScope(®) video laryngoscope has a 60° angled blade and the blade of the Truview PCD™ video laryngoscope has an optical lens that provides a 46° refraction of the viewing angle. Despite successful results using the GlideScope in adults, few studies have been published regarding its use in pediatric patients. We therefore tested our joint primary hypothesis that the GlideScope and the Truview PCD video laryngoscopes provide superior visualization to direct laryngoscopy and are non-inferior regarding time to intubation. ⋯ The Cormack-Lehane views attained using the GlideScope and the Truview PCD video laryngoscopes were not superior to views attained using direct laryngoscopy. Visualization with the GlideScope was significantly worse than with direct laryngoscopy. Use of the GlideScope and Truview PCD systems should be restricted to patients with specific indications.

The "hybrid procedure" is an alternative surgical palliation strategy for single ventricle congenital heart disease. The purported benefit is improved cognitive ability secondary to avoidance of cardiopulmonary bypass in the neonatal period when neuronal apoptosis is greater. It is unknown whether survival is improved after this procedure. Intraoperative hypotension is common in these patients, and we hypothesized that this hypotension was associated with mortality or morbidity. ⋯ In this patient cohort, we can show an association between short periods of intraoperative hypotension and mortality or return to the ICU on ECMO, but the importance of this is not certain.

In previous studies, insulin reversed the cardiac toxicity gradually induced by a continuous infusion of bupivacaine. In this randomized controlled study, we intended to simulate a more relevant clinical situation by injecting bupivacaine rapidly as a bolus to induce sudden-onset circulatory collapse in dogs. We then evaluated the insulin effect. ⋯ Insulin effectively reversed the sudden-onset circulatory collapse in dogs caused by an intravenous bolus injection of bupivacaine.
